Thread: Goto

I need to know how to use the goto command, I have a list of 'ifs'
something like this:


int main()
{
cout << blah blah blah...if blah blah blah press 1, if blah blah
blah press 2.

if (x==1)
cout << blah blah blah...if blah blah press 3, if blah blah press 4

if (x==2)
cout << blah blah blah...

if (x==3)
cout << blah blah blah...

if (x==4)
cout << blah blah blah...

how then if I needed to go back to if (x==2) from somewhere later on would I get back to it. I have been told to use the goto thing, I was wondering if I can get some more opinions on this.

Thanks.

This is a old example of creating spaghetti instead of well structured software. You should not use goto. It seems you are creating a large if-construction. I would propose to use the switch-statement and functions.

Whenever it happens that (x == 2), you just call the function that belongs to it.

The switch-statement:

Code:

switch (x)
{
    case 1:
        /* do something */
       break;
    case 1:
        /* do something */
       break;
    etc.
    ...
    default:
        break;
}
